|Title||Fix invalid rule match analyzation in WATO|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Compatible - no manual interaction needed|
The "Parameters of host/service" page and ruleset lists showed an invalid match result for rules which value evaluates to None. For binary rulesets (the ones that only have yes/no as value) the result was also not displayed correctly.
The ruleset matching of Checkmk during checking was not affected by this issue.
